=head1 NAME 

Makefile.PL - Makefile generator for GRID::Machine. Developer notes

=head1 SYNOPSIS

=over 2

=item * When working as a developer place in etc/ a script to customize your
environment, then do s.t. like:

           source etc/casianoperl5lib

to set the appropriate environment variables. Some variables to set are:

  PATH                  to execute scripts
  PERL5LIB              to find any modules required
  DEVELOPER             used by many skip tests
  GRID_REMOTE_MACHINE   the remote machine used for testing (see C<t/*.t> files)
  MACHINES              a white space string containing the machines
                        for the 'remotetest' target

=item * To build the documentation, you need L<Template> installed. Issue the command:

  $ make -f makepods

and the C<.pod> files will be built from the templates in C<tt2/>

=item * To build the *.html files:

   $ make -f makepods html

=item * To build pdf files:

   make -f makepods pdf

=item * To delete generated docs (*.html, *.pdf, etc.)

   make -f makepods clean

=item * To run the tests on remote machines:

   make remotetest

(Set the environment variable C<GRID_REMOTE_MACHINE> to the remote machine. 

=item * To use L<Devel::Cover> to study test coverage:

   make coverage

=item * To produce tags:

   make tags

=back

=head1 DEPENDENCIES

To use this C<Makefile.PL> as developer is convenient to have installed:

=over 2

=item * Template toolkit

=item * Pod2LaTeX

=item * LaTeX

=item * mpod2html

=item * Devel::Cover
